Title: A transfer mechanism for transferring a work-piece in a pressing machine
IPC: B30B1/26
Filed: 1961-11-13
Abstract: 932,985. Metalworking presses; blanks transferring. SMERALOVY ZAVODY, NARODNI PODNIK. Nov. 13, 1961 [Nov. 17, 1960], No. 40462/61. Class 83 (4). A transfer mechanism for transferring a workpiece between dies in a pressing machine, whose ram is operated by a crank mechanism, has gripping jaws driven from the crank, said jaws moving in a plane normal to the die axis. Jaws 6 are traversed in direction S (Fig. 2) by moving shafts 12 longitudinally, and transverse gripping motion is applied by rotation of shafts 12 which carry pinions meshing with racks in the underface of each gripper 6. Both axial displacement and rotation of the shafts 12 is derived from an eccentric pin 25 (Fig. 3) mounted on one of the press actuating connecting rods 22. Gripping movement of the jaws.-Movement of the pin 25 (Fig. 3) about an elliptical path e causes the ends of rocker 34 to oscillate about a centre 35 which, through link 36 and linkage 38, 39, 40 results in oscillatory rotation of the two shafts 40. Transfer movement of the jaws.-From the eccentric pin 25 there is driven a second linkage 26, 27, 29 to a bell-crank lever 30 which imparts a pure linear motion in direction S (Fig. 3) to the cross-member 14 rigidly attached to the shafts 12 (Fig. 2). The pivot points and lengths of various links in the jaw actuating mechanism are adjustable so as to vary the timing and magnitude of the jaw movements.

Title: Well tool
IPC: E21B33/12
Filed: 1967-09-11
Abstract: 1,149,808. Well packers. SCHLUMBERGER TECHNOLOGY CORP. 11 Sept., 1967 [12 Sept., 1966], No. 41354/67. Heading E1F. A retrievable bridge plug for a well bore has expanding grips for the bore wall which are urged against the wall by a pressure differential across the seal in either direction. The plug has a body 10 with a central bore 11 communicating with ports 12 (at the bottom) and 17 (near the top) in the body which facilitates sinking the plug in a liquid filled well. The plug is lowered by a tube string which engages a socket 14 and sleeve valve 20 for the port 17 at the top of the plug. Expandable grips 70 are resiliently mounted on a cage 50 mounted by buttressthreaded split nuts 57, 58 on the body 10. Further wall grips 53 hold the cage against rotation so that the body can be rotated to release the nut 57, the nut 58 then engaging threads 63 (Fig. 5B, not shown so that on continued rotation, the body is screwed down inside the cage and the grips 70 are pressed against the wall by a conical skirt 73 of a piston 36, and at the same time the plug seal ring 31 is compressed between the piston 36 and an abutment 27 on the body, and squeezed against the wall. When the tube string is disconnected from the socket 14 it also lifts the sleeve valve 20 to close the port 17, which would otherwise by-pass the seal 31. The top of the piston 36 is in communication with the bore below the seal 31, and the bottom of the piston is in communication, via bores 80, 81, 82 with the bore above the seal. Thus, if the pressure below the seal is greater than that above it, the piston will be urged downwardly and through the conical skirt 73, will increase the force on the grips 70. If the pressure above the seal is greater, then the pressure on the seal is transmitted by abutment with the flange 30 to the piston 36, and the resultant force is downwards. That is, the top of piston 36 is effectively always subjected to the greater of the two pressures, and partial areas beneath the piston are subject to each of the pressures, so that the resultant force is always downwards. In a modification, (Fig. 6, not shown), the flange 46 below the piston 36 is replaced by a free piston.

IPC: H02K15/085
Filed: 1967-09-11
Abstract: 1,192,469. Winding stator coils. BALZER & DROLL K.G. 11 Sept., 1967 [10 Sept., 1966], No. 41457/67. Heading B3A. A device for forming and holding the end turns of stator windings in dynamo-electric machines whilst protecting the slot insulation comprises finger-shaped end turn supports in combination with means for threading the supports in an arcuate movement along the stator end face between the face and the innermost end turns overlying the face. The end turn supports 1 are actuated by a linkage which operates about fixed pivot points 9, 11, 25 and is driven by a reciprocating lever 21, pivoted to a lever 22 about a pivot 24. As the lever 22 pivots about the point 25, a pivot point 15 on the support 1 follows a path 16, whereby the outer extremity of the support 1 is tilted horizontal, Fig. 4b (not shown). The support is then withdrawn radially with respect to the stator core and a roller 29 on the support is guided in a cam track 28 to assist this movement. As the radial movement begins pivot points 9, 13, 14 and 25, 26, 27 form two straight lines, Fig. 4h (not shown), and a pin 30 on an arm 10 engages in a slot 31 in the lever 22 to steady the movement of the linkage. In another embodiment, Fig. 5, supports 32 pivot about points 37, which are mounted on axially movable tracks 39 fixed on pressure plates 38. A stop pin 42 on the support 32 is held against a link 33 mounted on a fixed pivot 34 by a spring 41. When the tip of the support engages the end face of the stator 3, it slides therealong against the action of the spring and the pivot point 37 moves relative to the track 39. In a further embodiment, Fig. 6a, supports 43 are held by springs 46 in contact with bearing faces 47 of pressure plates 48. Movement of plates 45 towards the stator 3 causes the supports to slide down the faces 47 and along the stator surface under the end turns of the coils. Straight end turn supports (49) may be used in conjunction with any of the foregoing embodiments where protection of the slot insulation only is required, Fig. 7 (not shown).

Abstract: 901,391. Making helically seamed tubing. KUCKENS, A. Dec. 23, 1958, No. 41478/58. Classes 83 (2) and 83 (4). A machine for producing tubing with a helical welded seam from steel strip coming from a reel to a shaper or die extending obliquely to the feed of the strip to coil the same is characterized in that the reel rests on a strip feeder roll assembly and is driven by contact therewith. Strip la from a reel 1 resting on and driven by a take-off roll 8 and braked by means 10, is fed by the roll 8 and a counter roll 9 through guides 15, 15a to a coiling die 2, the axis of which is inclined to the axis of the reel 1. The tube thus formed in the die 2 by coiling the strip 1a is welded at its helical seam by outside and inside welding means 16 and 16a. The completed tubing may be severed into lengths as described in Specification 901,393 to which reference is made. In a modification, Figs. 2 and 4, the reel 1 rests on two take-off rolls 17a, 17b, or a single roll 17c, Fig. 3 (not shown), resting on a driven feeder roll 18 and the strip 1a is fed by the roll 18 and a counter roll 19 through guides to the coiling die 2. Between the feed rolls and the die edge, trimming cutters 27, 27a are provided and a welding device 25 for welding the rear end of one strip and the front end of a succeeding strip. A feeder plate 24, normally supported on rolls 23, can be introduced, for example by hand, between the rolls 18, 19 to feed the rear end of a strip up to the welding device 25, the rolls 18, 19 then being reversed to return the plate 24. To control the gap 1a<SP>1</SP> between adjacent edges of the wound strip, a gauge 28, engaging an edge of the strip 1a as it is fed to the coiling die, controls a motor 29 which, through rack means 30 rocks a frame 31, carrying the reel 1 and feed means about a pivot D to correct the entry angle of the strip 1a into the die 2. A pair of feelers 32 on the die 2 engage the edges of the strip which form the welding gap and control a motor 33 laterally to move the finished tube. The feelers 32 may control the motor 29. Specification 901,392 also is referred to.

To engage reverse it is necessary first to reenter the cross-shift neutral passage and then the 5-R channel, whereupon the stop arm 24a is again raised, permitting axial movement to R. In Figs. 3 to 5 the stop arm 24a is fast on the shaft 20, which can turn and slide in the fixed casing 1 to an extent limited by a fixed pin 22. A torsion coil spring 26 biases the stop arm downwards. In Figs. 6 to 8, not shown, the shaft 20 can slide but not turn and the stop arm 24a can turn on the shaft to an extent limited by a spring-loaded ball (32) engaging a camgroove in the shaft. In Figs. 9 to 11, not shown, the shaft 20 can turn but not slide and the stop arm 24a has limited sliding movement on the shaft. In Figs. 12 to 14 the shaft 20 can neither slide not turn, and the stop arm 24a has limited sliding and turning movement thereon. Figs. 15 and 16, not shown, differ in that the balk is effective for leaving R as well as 5. For this purpose the stop arm (24a<SP>1</SP>) is biased to a central position by a spring (29) on each side, and can turn and slide to a limited extent on a stationary shaft (20<SP>1</SP>).

Abstract: 977,215. Supporting lamps. MOLERICHARDSON (ENGLAND) Ltd. Oct.22, 1963 [Nov. 8, 1962], No. 42219/62. Heading F4R. [Also in Division B8] A lamp-supporting carriage especially for use in film and television studios, comprises a body carried on wheels running on parallel rails above the area to be lighted, an electric motor connected to at least one of the wheels for driving the carriage along the rails and a winch driven by an electric motor for winding a cable to adjust the height of a lamp carried by the cable. In the form shown, the body 1, Fig. 1, is U-shaped and is mounted on wheels 2 running on rails 8 and driven by an electric motor 3. Switches 6 on the ends of the body cut out the motor on coming into contact with buffers at the ends of the rails. A frame 11 is supported on pillars 12 on the body 1 and carries a winch 13 driven by an electric motor 14. The cables 20 from the winch are connected to the opposite ends of a rod 21 to which the lamp support 22a is pivoted. A telescopic mounting for the lamp consisting of vertical rods 17a-17e, 18a-18e and horizontal strips 19a-19j forming a series of mutually slidable frames is suspended from the frame 11, the uppermost strip 19a carrying a sleeve 23 which operates a switch 24 to cut out the motor 14 when the frames reach the upper end of their travel. A pair of rollers 26, Fig. 3, bear on the cables 20 so that slackening of the cable, e.g. on encountering a piece of scenery, closes a switch 29 to cut out the motor 14. In a modification, the spacing between the rails 8 and frame 11 is increased so that the lower strips of the frames are accommodated between the rails 8 at the upper end of their travel.
